Polypac Urethane Piston Seal

Polypac Urethane Piston Seal — Reliable Polyurethane Piston Sealing

Polypac Urethane Piston Seals are engineered to provide long-lasting, low-friction sealing for hydraulic cylinders and piston systems. Made from high-quality polyurethane, these seals offer excellent wear resistance, tear strength, and dimensional stability, making them ideal for heavy-duty and high-cycle applications.

Key Features

• High abrasion and tear resistance for extended service life
• Low friction to improve efficiency and reduce heat generation
• Wide temperature and pressure compatibility for varied environments
• Available in standard and custom sizes to fit specific cylinder designs
• Consistent material quality and tight manufacturing tolerances

Applications

These piston seals are commonly used in hydraulic cylinders for construction machinery, industrial presses, agricultural equipment, material handling, and mobile hydraulics. Their robust performance suits both stationary and mobile equipment under continuous operation.

Materials and Compatibility

Polypac uses advanced polyurethane compounds optimized for piston sealing. Urethane offers better abrasion resistance than many rubber compounds while maintaining good elasticity. Seals can be matched to hydraulic fluids commonly used in industry and are available in configurations that reduce extrusion and wear.
